ADSORPTION is the use of activated carbon on the adsorption of organic components, so that harmful components from the gas separation. The adsorption method is widely used in the treatment of organic waste gas, compared with other methods, this method has the advantages of high removal efficiency, complete purification, low energy consumption and mature process. The adsorption method is mainly applicable to the purification of organic waste gas with low concentration. The key to determine the efficiency of adsorption treatment is the adsorbent. The requirements for adsorbents are generally of a dense pore structure, large inner surface,https://www.dxdcarbon.com/ good adsorption performance, stable chemical property, acid and alkali resistance, water resistance, high temperature and high pressure resistance to air, etc. , commonly used adsorbents are activated carbon,products Activated alumina, artificial fluorspar, cinder and so on. Activated Carbon has the best performance and the most extensive application among the adsorbents currently used. In comparison, the pores of granular activated carbon are uniform, and the pores are 0.5-5 U M, and the specific surface area is 600-1600 m 2/g. The treated gas diffuses from outside to inside, because of the long distance, Global Wholesale Activated Carbonthe adsorption and desorption are slow, the granular activated carbon treated by oxidation has stronger affinity and is usually used in fixed bed activated carbon adsorption. The pores of fibrous activated carbon are all small and the specific surface area is large. It is adsorbed by the mutual attraction between molecules, and no chemical reaction takes place between them. It is a physical adsorption process. The pores open directly to the outside, the gas diffusion distance is short, and the adsorption and desorption are both faster,activated charcoal cost it's commonly used in adsorptive concentration.
